I currently have a payment form that is configured to use [url removed, login to view] as a merchant processor to process credit card payments.
I need it to be configured to work with other merchant providers. (i.e Payscout, USAepay, NMI, PayTrace) and I need to be able to easily switch from merchant to another to process payments.
I also want to add the option to process a check payment.
existing configuration page, form page and post page attached.
